4-in-1 Amplifier Input to 2-Out Stereo Speaker Switcher — Push-Button Selector (300W/ch)

Select between 4 power amplifier inputs with push-button control and route audio to two sets of stereo speakers. Output push-buttons let you open or close each speaker pair independently — both pairs can play at the same time, or you can turn any group off individually using the manual switches. Maximum power per channel is 300W. The input stage provides vacuum tube power amplifier signal no-load protection function. Input and output switching are manual and plug-and-play; switching is stable and will not produce audible clicks or noise between channels.
